vThe burner. casing 2 is open at its center,Y

thus providing an auxiliary air inlet and such air is directed'past and around'each semiciroular j et or nozzle in the burner plate Y bymeans 'of` a baflierplatef20, the formfof i f whichisbest shovvninFig. 2. Thisplate is attached or supported by anysuitablefmeans,

theheight of I the same is l very much less thanYV the height of the flame which 'would 'be j produc'edfwere all the gas'falloivedto mingle i M andform in effect'a single vflame;v rlThus, for

example, in Ythe"prese`nt burner lcomplete v only about an 'inch or. tvvo above vthe top of the baffle plate.` Y Y In order to concentrate and direct the rising "gases and to prevent the same from striking the' outer casingfand losing their heat, I provide a. second baffle plate 21v mounted upon? suitable lugs 22 on the Sides of the l'mrnerv casing. At'it's' topthe second baile plate 21 is" providedf'ivith an inwardly curved flange 2 3vvhich Mdirects the products of combustion tovvard the center ofthe burner .casingftovvar'd which point the Haines passfupivardly'through the heating coils, Which are not sho'vvn.

These desired results are obtained in my device by initially directing the.

Yindividual flames horizontally properlyr dis-v tributing the auxiliary air to the outlets of the burner passages 18. It Will be noticed that this auxiliary air is practically admitted through the burner itself, the contour of the burner openings being such that the additional air is supplied to,` and mixed with, each individual fiame.

Other modes of applying'the principle of my invention may be remployed instead of the one explained, change being made as regards the mechanism herein disclosed, pro' vided the means stated by any of the following claims orv the equivalent of such stated means be employed.

I.. therefore particularly point out and distinctly claim as my invention l.V The vcombination with an outer casing forming a heating chambenof a burner casing mounted Withinv andin contact Withthe Wall" of said outer casing, said burner casing having an'annular chamber therein open adjacent to its top, a gauze screen interposed in "suchchamber, a mixing conduit connected to such annular chamber at its bottom, and meansadapted to break up the gas and fair issuing fromrthe open top of such annular chamber into 'a plurality of individualujets, and to cause completeand separate combustion of each jet.

2. The combination with an outer casing forming a heating chamber, of a burner casing mounted WithinV and in contact With the wall of said outer casing, said burner casing having anannularchamber therein open adja'centto yits top,'a gauze screen interposed in such chamber, a mixing conduit connected to such annular chamber at its bottom, and a distributing plate mounted on said burner casing and'having a plurality of variously directed openings, each adapted to produce an' Yindividual ame.

5. The combination with an outer casing forming a heating chamber, of a burner casing mounted Within and in contact With the Wall of said outer casing, said burner cas ing having an annular chamber therein open adjacent to its top, and having an aperture in its center, a mixing conduit connected to such annular chamber at its bottom, a distributing plate mounted on said burner casing and formed with a continuous rovvl of outwardly directed, horizontally discharging openings, each adapted to produce an individual and separate ame, and means adapted to direct the auxiliary air entering such central aperture in said burner casing past such openings in said distributing plate.
